Up to [local] / src / usr.bin / aucat

Allow any program using aucat to act as MMC slave and MTC master
transparently.  Multiple audio applications can be started
synchronously from external software/hardware supporting the
standard Start/Stop/Relocate messages. The server clock is exposed
through MTC, allowing non-audio software/hardware to be
synchronized to audio applications.
